6 Claims.

This invention relates to liquid dispensing devices and is more particularly directed to a device to dispense predetermined, measured quantities of liquid by causing the'liquid to flow into an intermediate receptacle of known capacity and subsequently discharging the liquid from the intermediate receptacle.

' The primary objectof the invention is the provision of a simple and efficient valve means to control the flow of liquid into and out of an intermediate receptacle of known capacity in a manner such that at one stage of the operation the liquid inlet control valve and the liquid discharge control valve are both closed. 7

Another object of the invention is the provision of air passages disposed in such a manner that air will flow freely into the primary receptacle during the filling of the intermediate receptacle and will flow freely into the intermediate receptacle during the time its contents are being discharged.

Other objects and advantages of the invention will become apparent as the description proceeds, reference being had to the accompanying drawing, in which FPg. 1 is a central vertical section with parts in.full; Fig. 2 is a view similar to Fig. 1 showing a difierent application of that figure with the parts moved to discharging position, and Fig. 3 is a view similar to Fig. 1 with the parts in an intermediate position.

Referring to the drawing, ,a cylindrical measuring vessel 50 is fixed to the top of a bottle either by screw threads, as shown in Figs. 1 and 3, or by a cork, as shown in Fig. 2. Valves are carried on a stem 52 and include cylindrical parts 54, each terminating in poppet type flanged seating extensions 56. The body 50 is provided on its interior with valve receiving portions 58 and 60, the latter also forn'nng a closure for the outer end of the body. The valve receiving por-. tions have cylindrical bores closely corresponding to the diameters of the cylindrical valves 54 with which they cooperate. The closure Bll'is provided with a relatively large, hollow, dome-shaped" interior space 6i which provides a reservoir or storage space for air during a pouring operation.

A relatively large pouring spout 62 is located at one side of the end of the member 60, and a relatively small vent port 64 communicates with the air reservoir 6| at one side thereof in a posi-. tion such that when the pouring spout 62 is held in discharging position the port is vertically displaced therefrom at a point considerably above the pouring spout so that the liquid will pass through the spout 62 and air will enter through the port 64 to the interior of the measuring chamber 50.

An operating button 66 is carried on the outer end of stem 52 and the stem and its associated valves are biased by a spring 68 to stand in a position such that the interior of the measuring chamber is in opening communication with the interior of the bottle with which the device is used.

As shown in Fig. 3, the axial distance between the valves 54 is such that on initial displacement by pressure on the button 56, the valve 54 which controls communication between the bottleand the interior of the chamber will be closed before seating and prior to the time that the opposed valve opens communication between the interior of the chamber 50 and the pouring spout 62. In this way continuous pouring by manipulation of the stem 52 is prevented, so that any quanttiy of the contents of the bottle can be dispensed in measured amounts while the bottle is held in pouring position as shown in Fig. 3.

In operation, the outlet valve 54 contacting the portion is held in normally closed position by the spring 68. The inlet valve 54 contacting the portion 58 is held in normally open position by the spring 68. When the bottle is inverted, liquid thus flows into and fills the measuring chamber. The operating button 66 is then pressed and the inlet valve closes the communication between the bottle and the measuring chamber before the outlet valve opens. Further depression of the op erating button opens the outlet from the measuring chamber and permits the liquid to flow into the dome-shaped chamber and out the pouring spout 62. When the outlet valve is thus opened, air enters the dome-shaped chamber through the vent port 64 and flows into the measuring chamber around the portion of the outlet valve adjacent the vent port. The air thus entering the measuring chamber while it is being emptied of liquid will enter the bottle while the chamber is being filled. As soon as the measuring chamber has been emptied of liquid, the operating button may be released and the cycle of operation repeated while the bottle is inverted and held in pouring position, as shown in Fig. 3.

Having thus described our invention, what we claim as new and desire to secure by United States Letters Patent is:

1. In a device of the character described, a body having a liquid inlet valve-seating portion at one end and a liquid outlet valve-seating portion at the opposite end, a measuring chamber disposed between said portions, plug valves to engage each of said seating portions, manually operable means carrying said valves, said valves being carried in fixed spaced relation on said means intermediate said seating portions to close said openings simultaneously and to open alternately, and a dome-shaped chamber in said body above said measuring chamber in which is located a relatively small air inlet opening and a relatively large pouring opening.

2. In a device of the character described, a body having a liquid inlet valve-seating portion at one end and a liquid outlet valve-seating portion at the opposite end at least a portion of each of said portions being cylindrical, a measuring chamber disposed between said portions, plug type valves adapted to fit into the cylindrical portion of said portions, manually operable means carrying said valves, said valves being carried in fixed spaced relation on said means intermediate said valve seating portions to close both of said seating portions simultaneously and to open alternately, and a delivery chamber'in said body above said measuring chamber in which is located a relatively small air inlet opening and a relatively large pouring opening.

3. In a device of the character described, a body adapted to be connected to a bottle, said body having a measuring chamber with a liquid inlet passageway adapted to be placed in communication with the bottle and an outlet passageway at least a portionof each of said passageways being cylindrical, flanged plug type valves adapted to fit into the cylindrical portions of said passageways, manually operable means carrying said valves in spaced relation intermediate said passageways, said valvesbeing spaced on said means to close both passageways in an intermediate position and to open communication from the bottle and from the chamber alternately in their extreme positions when a valve flange engages one of said passageways, the body being shaped to provide a delivery chamber communicating with said outlet passageway and having a relatively small air inlet opening into the delivery chamber and a relatively large pouring opening from said delivery chamber.

4. In a device of the character described, a body adapted to be connected to a bottle, said body having a measuring chamber with an inlet passageway adapted to be placed in communication with the bottle, and an outlet passageway, said passageways having valve-seating portions facing each other, a delivery chamber connected with the outlet passageway, a plunger journaled for longitudinal movement through the chamber, valves carried by said plunger intermediate said valve-seating portions, and spring means releasably holding one of said valves against the valveseating portion of the outlet passageway.

5. In a device of the character described. a body having a liquid inlet valve-seating portion at one end, and a liquid outlet valve-seating portion at the opposite end, said body being otherwise imperforate, a measuring chamber disposed between said portions, plug valves to engage each of said seating portions, manually operable means carrying said valves, said valves being carried in fixed spaced relation on said means intermediate said seating portions to close said openings simultaneously and to open alternately, and a dome-shaped chamber in said body above said measuring chamber in which is located a relatively small air inlet opening and a relatively large pouring opening, both said openings in said dome-shaped chamber being above the path of movement of the valve controlling the liquid 'outlet from said measuring chamber whereby air only enters said measuring chamber after first entering said dome shaped chamber and in passing said outlet valve.
